FIELD: process engineering.
SUBSTANCE: proposed crusher can be used for processing of ores and rocks in mining and chemical industry for processing of hard minerals. Crusher comprises cylindrical housing 2 with vertical rotors, top loading opening 1 and bottom unloading opening 7. Breaking-down rings are arranged at housing inner wall. Spinning screw deflectors are arranged under rotors ahead of unloading opening 7. Screw deflectors 6 deflect multiple times the primary crushed bulk back from bottom to top into crushing chamber 4 to increase the crushing degree.
EFFECT: perfected design.
